Yes it is possible. My previous shop car made over 770rwhp on 15 lbs of boost with a TC76MPS turbo. This was with a TH400 and 9 inch. The PT88 has the potential to make more.

how much would a 76gts make then, im on the4 fence for buying a turbo,. the pt88 looks much larger on the exhaust side(housing) will the 76gts be too restrictive to get the exhaust out?

The 76gts will work also for your setup just fine. I have used the 76gts on one of my kits and a 370 to 750rwhp easy. Just watch the back pressure. Its also what you want down the road. Remember boost is a drug...lol

Joel is correct. It is really about what your goals are and what they will be. A 76mm turbo will hit 750rwhp easy. The PT88 will too, and then some.

If 3.0 inline sixes can do it, a LS1 sure can with even better flowing heads and cubes

Why don't you spot your et goals instead of you hp goals. That pt88 would haul some *** but the tc76 on that motor would too. Depens on how far you want to push it.

it is a little of everything setup, i just want to make 1000 hp on the motor for advertising reasons, anywhere in the 9s would be fine, but really all around here is 1/8 so 6s would be easy to fall into, 5.9s i think would be a tone of work.

my friend has one on has camaro and it had a lot of measured back pressure and from what ive read a lot of other people have had the same problems......I ran a pt88 for a few years and I mawxed out my set-up at that time with about 24 psi and that was good for about 900-950 at the wheels..more could be gained if I tweeked the set-up.
